Project #58052 - Java Program-BST Trees

21 Computer Tutors Online

Required: implement methods for the following BST operations: search, insert, tree-traversal (pre, in, and post orders), count (leaves, internal nodes), height.
Approach: Generate a BST by repeatedly inserting at least 20 keys (starting from an empty tree). Then, perform the following operations in the prescribed order showing the results after each of the following operations (or implement a menu with choices. Displaying the menu and the results in the output window of the IDE is fine): NOTE: USER INPUT IS REQUIRED, NOT SIMPLY A HARDCORE OF THE BINARY OPERATIONS BELOW. USER MUST HAVE IDE MENU TO CHOOSE ANY OPTION AFTER EACH OPERATION. A short explanation of classes as well.
